Other than that, the only place in legion, if its true that everything has to start on legion content, where anything rune related could be, is probably in storheim, maw of souls, or that helheim instance. I do not think its going to be in halls of valor, since the weapon and its description appears sinister.
Also this showed up in the PTR today:
Pet Battles
Raiding with Leashes IV
Delve into Ulduar, Trial of the Crusader, and Ice Crown Citadel in search of rare pets and the chance to do battle with a new Celestial foe!
So its both new legion content, but based on places related to frostmoure and dark runes.
